Man's ability to control illumination is magical in itself but is seldom experienced as such because light switches are purely functional and generally don't stir up imagination.

The magical lamp depicted in the movie below is an example of Magical Interaction an approach towards interaction design aiming to stimulate people to use their own imagination in the interaction with a product.

As products are becoming more active and at the same time less visible in the environment, this enables more subtle and richer interactions between people, products and the environment. The core of Magical Interaction is in the elegant use of technology. The interactive magical lamp responds to an ultra-sound signal which is emitted by a special bracelet worn by the user.
